What it needs is two or three well-established franchise entries such as Assassin's Creed, GTA or ideally Call of Duty, along with some of the more universally-liked first party series. Zelda would be perfect, most Xbox/PS gamers I know still admire Zelda, and F-Zero would also be quite appealing to non-Nintendo players. Mario, Kirby and DK don't seem to garner a lot of respect outside of the Nintendo playerbase, although a Mario game is generally a given at launch.

Personally I'd buy the console for £300 if the only games ever released were Mario Kart and Smash Bros :]

Just a short, off the top of my head list (I know I'll forget some)-Smash Bros.-Star Fox-FzeroPikmin 3-Some new Solo Yoshi game-Maybe a game starring Bowser-Sonic Adventure 3...with Chao (don't hate)-Mario Kart-Several Mario sports games (I know it's been done, but they can be a lot of fun)-New Mario 3D game-Some crazy new Wario Ware game-Of course a new awesome Zelda-Metroid (Prime type of game)

There can only be one, like in that foreign movie where there could only be one, and in the end there is only one dude left, because that was the point.

I know this is a "Dream" launch lineup, but realistically, this is what I hope to see.

-MARIO (I don't care what it is, Mario needs to be a launch game, like it used to be. Nintendo surely should have learned that lesson by now)-Pikmin 3 (Most likely will happen)-New F-Zero game-New Metroid game-New Star Fox game-At least one HD remake, Wind Waker?

Some extra thoughts, I highly doubt we will see any form of Zelda, besides what I said above. The Legend of Zelda is almost always a no-show for launches. They usually come later, so I'm fine waiting for the Zelda HD we all want. Besides those first party Nintendo games, I want to see all that 3rd party support the Wii U seems to be promising. Nintendo shouldn't rely on it like they did with the 3DS launch (and we all know how that went) but they should have a good mix of both 3rd party and some strong titles with Nintendo characters we want to see in HD.

Super Mario 64 2/Universe (jumping into paintings, punching/kicking mechanics needs to be back and secret bosses hidden in dungeons like Zelda style)No More Heroes 3GTA (Nintendo needs an other good sandbox title that doesn't involve with drugs)F-Zero (Needs good online play)Sonic 2d/3d title (Same gameplay like generations and colors)Pokemon Adventure (Needs to be ether mature or target to neutral audience to all ages, still a good concept but it had two obsolete titles)Sonic 4 Episode 2 (Meh why bother looks better then the first)Digimon (Hack and slash with RPG elements thrown in)Cave Story 2Wario 3D Title (Loved the gamecube title)Black Rock Shooter (a heroine title on psp that never got lunched outside of Japan)Dynasty Warriors Transformers (Needs to be a better adaptation unlike the movie games and war cybertron which I'm not satisfy with)Dynasty Warriors Gundam collectionMother 1 and 2 remakeMech Fighting CrossoversArcade shoot em ups (Nintendo is some what lacking recently)
